(E)-1-Chlorobut-2-ene Usage And Synthesis

Uses

Crotyl Chloride is a useful intermediate used in the preparation of crotyltrichlorosilanes and in other crotylsilylation related reactions

Uses

Crotyl chloride was used in kinetics measurements of reactions of atomic chlorine with series of unsaturated aldehydes and ketones at 298K. (E)Crotyl chloride was also used in the preparation of (E)-crotyltrichlorosilane.

General Description

Crotyl chloride reacts with trichlorosilane in the presence of tertiary amine and copper salt to give the corresponding allyltrichlorosilane.
